President Donald Trump continued a long-running feud with London's mayor on Monday, criticizing him on Twitter for the second day in a row in the wake of the deadly van and knife attack in the city.

Trump said London Mayor Sadiq Khan had offered a "pathetic excuse" and "had to think fast on his 'no reason to be alarmed' statement."

Trump's tweet renewed his mischaracterization of Khan's statement to London residents following the attack that left seven people dead and dozens injured. The mayor had told London residents not to be concerned by a stepped-up police presence in the city after the incident.

Khan said Monday the U.K. should cancel Trump's offciail state visit after his critical comments.

"I don’t think we should roll out the red carpet to the president of the USA in the circumstances where his policies go against everything we stand for," Khan said to Britain’s Channel 4 News.

When asked how relevant Trump's tweets are, White House spokeswoman Sarah Sanders said "they matter in the sense that they give him a communications tool" but said "the media obsesses over every period, dot."

Sanders also said Twitter is important so Trump can "communicate directly to the people without the bias of the media."

She said she is not aware of anyone vetting Trump's tweets before they are published.

In a Sunday tweet, Trump mischaracterized Khan's remarks by suggesting the mayor had said there was "no reason to be alarmed" about the attack itself. Khan's spokesman said he was too busy to respond to Trump's "ill-informed" tweet.

Khan told the BBC Monday that Trump's comments will not "divide our communities."

On Monday, a spokesman for Khan said: "The mayor is focused on dealing with Saturday's horrific and cowardly attack and working with the police, the emergency services and the Government to keep London safe."

Asked if Trump was wrong to make the comments, British Prime Minister Theresa May said at a news conference Monday that "Sadiq Khan is doing a good job and it's wrong to say anything else — he's doing a good job."

Sanders said Trump was not "picking a fight with the mayor of London at all." She also pushed back against criticism that the president had mischaracterized Khan's remarks, saying that "the media wants to spin it that way."

Asked if Trump was criticizing the mayor of London because he is Muslim, Sanders said that was "utterly ridiculous."

Trump's latest missive at Khan was part of several Monday morning tweeted statements from the president. Trump also lashed out at his own Justice Department for seeking a "watered down" version of the travel ban he signed in March instead of a broader directive that was also blocked by the courts.

The war of words was the latest episode in a long simmering conflict between Trump and Khan, a Muslim who was elected as London's mayor in May 2016. After his election last year, Khan tweeted criticism of then-candidate Trump's rhetoric, saying his "ignorant view of Islam could make both our countries less safe. It risks alienating mainstream Muslims." Trump later challenged Khan to an IQ test during an interview on ITV.

Senior White House adviser Kellyanne Conway on Monday condemned what she called the media's "obsession with covering everything he says on Twitter and very little of what he does as president."

In an appearance on NBC's "Today Show," Conway said people in England had tried to inform authorities about the suspects before the attacks happened.

"If you're going to see something and say something, it has to be followed by, do something," she said. "And this president is trying to do something to protect the people of this country."

Trump said he had spoken with May to express America's "unwavering support" and offer U.S. assistance as the British government works to protect its citizens and bring the guilty to justice.

British authorities have named two of the three suspects in the attack. The three suspects were shot dead by police officers within minutes after they drove a van into pedestrians on the bridge and then stormed pubs and restaurants, stabbing anyone in their path.
